Abstract

1335184 Modified TiO 2 LAPORTE INDUSTRIES Ltd 16 Dec 1970 [24 Dec 1969] 62927/69 Heading C1N Pigmentary TiO 2 is produced by hydrolysing a solution of Ti sulphate to ppt. hydrous TiO 2 , incorporating rutile-inducing seeds with the sulphate solution and/or with the ppt., treating the washed ppt. with 0À02-0À5% by wt. (calo. as oxide) in total of one or more of Be, Al, Mg, Zn, Li or compounds thereof, 0À05-1% by wt. (calc. as oxide) in total of one or more of Na, K, Rb, Cs, Li or compounds thereof, and at least 0À7% by wt. (talc. as (NH 4 ) 2 SO 4 ) of ammonium compound(s), adjusting the pH if necessary to 6-10, and calcining at 750-1000‹ C. The additive compounds may be sulphate, chloride, nitrate, basic chloride or sulphate, carbonate, bicarbonate, oxide, hydroxide, formate, acetate, oxalate, benzoate, metal alkyl or alkoxide. They may be added to an aqueous slurry of the TiO 2 , before and/or after pH adjustment, as an aqueous solution or solid. The ammonium compound may be NH 4 OH or (NH 4 ) 2 CO 3 or may be formed in situ from gaseous NH 3 . pH adjustment may be effected with the NH 4 compound and/or with alkali metal or alkaline earth metal hydroxide or carbonate. Calcination may be carried out in a rotary kiln or muffle furnace with a rate of increase of temperature of less than 1‹ C. per min. The product may be wet milled and leached and the leach liquor used to treat fresh TiO 2 hydrolysate. Various methods of making the seeds are mentioned. In comparative examples, Si, Sn, Ca, Zr, Cd and Si are incorporated with the ppt.
